“…Additional formal Chlorococcum species descriptions for strains distinguishable solely based on DNA sequence data would probably create an even more complicated taxonomic situation for this polyphyletic genus. Some Chlorococcum species have been reported to accumulate abundant amounts of lipids (as it was observed in the case of strain K2/5) and are thus considered as potential algae for biofuel production (Mahapatra & Ramachandra, 2013;Prabakaran et al, 2019). Chlorococcum minutum produces biological hydrogen (Paramesh et al, 2018), while other strains within this genus could be potential natural source of Bvitamin (Fujii et al, 2010).…”

Chlorococcum is a coccoid green algal genus, which contains almost 50 species. The genus is polyphyletic, but in a traditional sense, the cells are coccoid and non-motile with a cup-shape chloroplast in the vegetative stage, while the spores have chlamydomonad appearance. They are distributed worldwide mainly in terrestrial habitats, and the biotechnological potential of several strains has also been reported. In this study, three new green algal strains from a shallow temporary freshwater lake in Hungary are characterized using microscopic (light and transmission electron microscopy) and DNA-based methods (phylogenetic analysis of the ribosomal ITS region, the 18S ribosomal RNA and rbcL genes, and ITS secondary structure comparison). Based on the obtained results, one of the three new isolates is considered to represent a new species, which is described here as Chlorococcum szentendrense sp. nov.

“…8 studied the enzymatic production of biodiesel from waste oil using enzyme as catalyst. Biodiesel was also prepared from different cheap sources [9][10][11][12] adopting different technology [13][14][15][16][17] by using chemical catalyst as well as biological catalyst Success of the production of biodiesel lies in the minimum process cost with least process hazards. Biological catalyst plays significant role in this aspect.…”

Recycling of enzyme for the preparation of biodiesel from rice bran oil fatty acid distillate (RBOFAD) is a novel technology along with a cost effective ecofriendly process. Biodiesel has been recognized as future fuel which can be prepared from cheap raw materials in the presence of catalyst enzyme maintaining certain reaction parameters. In our study, Novozyme 40013 (lipase from Candida antarctica) has been used and recycled for this purpose with special emphasis on the productivity of the process. Initially, the process parameters are optimized for the synthesis of biodiesel from RBOFAD and methanol at a definite temperature with a molar ratio of 4:1 (alcohol:RBOFAD) for 180 minutes at 5% concentration of enzyme. After that, enzyme has been successfully recycled twenty times in laboratory scale for biodiesel production by applying the optimized reaction parameters. The main emphasis for recycling of enzyme is to reduce the production cost along with minimization of process hazards. The physical properties of Recycling … Sumit Nandi et al.

This manuscript reports for the first time a heterogenous catalytic route to monoglycerides (MAGs) from microalgal oil. Microalgae is an important biomass source with high‐value applications, such as food ingredients with essential fatty acids. To date, the glycerolysis of microalgae has only been investigated for a microbial oil (Schizochytrium sp.) using enzyme catalysis. However, the use of enzymes on a large scale is currently economically impeditive and requires highly selective lipases. In this study, metal oxides were screened and the reaction conditions optimized for rapeseed oil. The optimized conditions were then used to investigate the production of MAGs from Scenedesmus sp. microalga. The most promising catalyst was found to be MgO/KOH, which gave a 44% yield. Comparing two reaction systems (low temperature 70°C/atmospheric pressure and high temperature at 200°C/20 bar), it was found that the latter has a superior performance. Due to the stability of the product in air, the presence of an inert atmosphere is essential to achieve high yields.
